We gained an integrated stored current of 10.3 A*hrs between 9:19 AM (Oct. 12 ) and 8:39 AM (Oct. 13). Average beam current during this period was 441 mA.

Tuning of the beam orbit (measurements of the betatron functions and single-kick response) was carried out during the daytime. Short study on ion trapping was also carried out in the night.

Vacuum conditioning continued in the midnight.


Beam current in this morning. Tuning of the beam orbit is under way.


Vacuum pressures in the storage ring (at 10:29 AM). Since the beam current is small, the pressures are very close to the base pressures. Beam current: 11.1 mA, average pressure: 0.33 nTorr.
